I have a question about a hard bump that I have. It is located above my left breast, below my collar bone. It is really hard, and raised up. I can see it just looking in the mirror. It feels almost like a bone. But I don't think it is. It is really hard to describe. It isn't perfectly round, maybe kind of like an oval, about an inch (maybe a little less) in diameter, and it isn't moveable at all. Any feedback would be much appreciated!!!
